Abstract: THREADED LAMP ADAPTER     Abstract of the Disclosure An adapter for permitting a lamp to be threaded into a light socket while preventing damage to the socket through application of excessive threading force includes a threaded sleeve rotatably mounted on a cylindrical body and conductive securing means for preventing longitudinal movement of the sleeve with respect to the body, the secur-ing means being urged into sliding electrical contact   with the sleeve and being connected to an electrical conductor for maintaining electrical continuity between the sleeve and an energizing terminal of the lamp.  A cam on the ring cooperates with an opening in the sleeve for permitting relative rotation between the sleeve and body in one direc-tion when a threshold torque is exceeded to prevent damage to the socket but preventing relative rotation in the other direction so that the lamp and adapter can be threaded out of the socket.

Abstract: ABSTRACT     A cell culture medium not relying on fetal bovine serum as a necessary component is disclosed.  The medium optimally comprises from about 80-90% of a chemically defined nutrient medium and from about 10-20% of a natural biological fluid which has been treated by contact with "feeder" culture of smooth muscle cells for about 24 hours.  The treatment may involve only natural fluid or such fluid in admixture with nutrient medium.  Thymidine is then added in an amount such that its final concentration is between 10-4M and 10-6M. Such medium has been found suitable for the growth of mammalian cells, including mammalina endothelial cells.  Additionally, lots of fetal bovine serum found unsuitable to support cell growth may be treated by contact with smooth muscle cells for about 24 hours and thereby converted to acceptable lots.

Abstract: ABSTRACT OF THE DISCLOSURE     This invention discloses a temperature-compensated measuring system which employs an internal signal-processor to provide high accuracy measurements, correct over a wide range of temperatures.  In a calibration mode, the system employs the signal-processor to provide mathematical constants used to generate a temperature-compensation function.  In a measurement mode, signals representing the uncompensated quantity and the system temperature are supplied to the signal-processor, which uses them to generate a temperature-compensation function from which it produces a high-accuracy temperature-corrected value of the measured quantity.  In various forms, the invention can be used to measure tem-perature-compensated force, pressure or acceleration.

Abstract: ABSTRACT OF THE DISCLOSURE     A new and useful composition of matter, solid at room temperature, is disclosed, comprising:(1) an effective amount of a suitable nucleating agent substantially uniformly dispersed in (2) a suitable pressure-sensitive adhesive for encapsulating a temperature-sensitive solid mixture having a given nucleation efficiency and which melts at a predetermined temperature, whereby the suitable nucleating agent is (a) inert to both the pressure-sensitive adhesive and the temperature-sensitive solid mixture, and (b) capable of raising the nuclea-tion efficiency of said solid mixture.  The novel composition of matter overcomes the extreme super-cooling achieved by temperature indicating compositions of matter in U.S. Patant 4,232,552 (which change color with a change in phase) without the use of classical nucleating agents being employed in such temperature-indicating compositions of matter. The novel adhesive composition of matter has been found to be especially suitable in conjunction with a preferred 552 temperature-in-dicating composition of matter comprising pinacyanol iodide dissolved in a solvent comprising ortho-chloronitrobenzene and ortho-bromonitrobenzene.  An especially suitable novel adhesive of the instant invention comprises 0.5 to about 5.0 phr talc in polyisobutylene.

Abstract: Abstract of the Disclosure A multilayer photoconductive assembly with an intermediate heterojunction.  The assembly comprises a conductive substrate, a thin semiconductive layer formed of a material of one carrier polarity, which material has a narrow band gap.  This layer is in substantially ohmic (low-resistive) contact with the conductive substrate.  A light-absorbing layer is formed of a semiconductor which is thicker than the first layer and is of a carrier polarity opposite to the polarity of the first layer.  The material has a band gap wider than the band gap of the first layer.         The first and second semiconductive layers form a rectifying heterojunction therebetween.  This enables the assembly to have a tremendously increased dark resistance and produces an assembly enabling high-speed electrophotography.

Abstract: ABSTRACT A data processing system requiring fixed point and floating point computation operations comprises an arithmetic computation unit for providing fixed point arithmetic computations and a floating point computation unit for providing floating point arithmetic computations.  A control store supplies microinstructions to control the operations of both the arithmetic computation unit and the floating point computation unit.  Both units are responsive to several commonly shared control fields of the microinstructions during their respective operations and the floating point computation unit is also respon-sive to at least one additional control field during its operation.  The complexity and cost of the system are reduced over systems which require two complete separate control stores or two completely separate sets of control fields of a single control store.

This is a multi-purpose, low-profile desk accessory in which a horizontally oriented flat base sheet is formed with upstanding walls which define a plurality of shallow storage wells, including one for the storage for a roll of tape which is horizontally oriented, and another for the storage of a flat stack of unbound note paper.  Suitable means are provided for twisting the tape 90° as it comes off the tape roll. Above these shallow storage wells are upper decks which pro-vide additional storage space, some of which is specifically dedicated to such office implements as a ring-bound calendar, and possibly an ash tray or card file. Alongside the shallow lower level and upper level storage facilities is an elevated structure which includes deep wells for the storage of paper clips and similar desk implements, and another deep well for storing elongated writing instruments such as pens and pencils in a horizontal attitude.  The latter has a special floor shape which tilts the pens and pencils upwardly so that they can be easily grasped and removed for use.

Abstract: ABSTRACT OF THE DISCLOSURE A robot control apparatus for controlling the movement of an arm of a robot with respect to a workpiece transported upon a pallet moving down an assembly line, wherein the position of the arm of the robot is compensated for in accordance with the position of the workpiece.  A reference position memory stores a reference position of one of the pallet and workpiece.  A position detector detects the position at which the pallet of workpiece is clamped along the assembly line.  A difference between the outputs from the reference position memory and the position detector is used to correct a value stored in a work position memory to thus provide the output data which controls the movement of the arm of the robot.

The seal is located in close proximity to a gas permeable bearing also disposed between the shaft and the partition and located in the relatively lower pressure region.  The seal permits limited leakage gas flow toward and through the bearing and pieces of seal material abraded during shaft rotation tend to entrain in the leakage gas flow. A baffle is disposed on the shaft between the seal and the bearing and defines a portion of a serpen-tine path for the leakage gas flow.  A contamination trap containing a self-supporting adhesive material is formed on the baffle perpendicular to a portion of the serpentine path so that while the leakage gas turns 90° at the trap, the heavier particles of abraded material impact on and are captured by the adhesive material.
